DOCTER DOCTER®basic 3-12x56 - Manual (Page 11)

Initial operation
Inserting the battery
First of all, unscrew the cap of the battery compartment (1). Then place a lithium battery
CR2032 (included in the scope of supply) with the positive terminal pointing upwards
onto the battery compartment and depress in the centre until it engages. The inscription
on the button cell must be legible.
Removing the battery
First of all, unscrew the cap of the battery compartment (1). Now the button cell can be
removed by pushing down on the edge of the cell until the battery disengages and pro-
trudes.
Switching the reticle illumination on / off
To switch on the reticle illumination, take hold of the control unit (2) with two fingers and
pull it out. When it is switched on, a red marking is visible and provides information
about the operating status of the rifle scope.
Pushing in the control unit (2) switches off the reticle illumination.
Brightness control of the reticle illumination
DOCTERbasic rifle scopes are equipped with a dimmable daylight illuminated reticle.
The intensity is adjusted via an up and down movement of the control unit (2) that is lim-
ited by stoppers. To increase the illumination intensity, the control unit is moved in direc-
tion of the (+) marking and held there. To reduce the illumination intensity, the control
unit is moved in direction of the (–) marking and held there. On reaching the minimum or
maximum end position, the illuminated reticle starts to blink. The set brightness is re-
tained by releasing the control unit.
Automatic deactivation
If the control unit (2) is not activated within a period of approximately 3 hours, the reticle
illumination switches off automatically. To reactivate the reticle illumination, switch the
control unit (2) off and on or activate the intensity adjustment.
Memory function
The electronics of the reticle illumination is equipped with a memory function. The
brightness value set last before the device was switched off is saved and is immediately
available when the device is switched on again.
Battery warning
If a low battery voltage has been detected, a warning is given by constant blinking.
